If you've been following the Sony, North Korea and the US government
saga then you should know what this is about. But let me give a brief
summary because I'm about to board a flight.

Sony Pictures released a movie called The Interview, a comedy about a
fictional assassination of North Korean leader, Kim Jong Un.. North
Korean didn't find it funny and hacked into Sony's computers, rendering
thousands of computers inoperable and forced Sony to take its entire
computer network offline. That wasn't enough, they then threatened
terror attack on US citizens if Sony doesn't cancel showing the movie,
forcing Sony to pull the interview from theaters and losing almost
$200m. Then the US govt got involved and told Sony to go ahead and
release the movie, that they don't take lightly to threats and promised
to retaliate for the attack on Sony. It looks like they've kept their to
promise. North Korea is currently offline. Lol

"Internet connectivity between North Korea and the outside world is
currently suffering one of its worst outages in recent memory,
suggesting that the country may be enduring a mass cyber attack a few
days after President Obama warned the US would launch a "proportional
response" to North Korea's hack against Sony

North Korea, which has four official networks connecting the country to
the Internet -- all of which route through China -- began experiencing
intermittent problems yesterday and today went completely black,
according to Doug Madory, director of Internet analysis at Dyn Research in Hanover, New Hampshire." Bloomberg reports.
